背面の脊椎 (合計): 0; 肛門の骨 0. One barbel on chin, one on tip of snout, and one at each of the anterior nostril. First dorsal fin ray very elongate, followed by a row of small, fleshy filaments. Color varies from dusky to pale.
Sedentary bottom dwellers on muddy sand between patches of hard substrate, or on the soft, smooth ground of deep sinks on the continental slopes of both sides of the North Atlantic. Feed on flatfishes, amphipods, decapods, copepods, mysids, shrimps, isopods and other small crustaceans. Spawn in the Baltic Sea (Ref. 35388).
